Given:

Two figures.

To find:

The area of the shaded regions for both figures.

Solution:

In first figure, the shaded area is a triangle with base 15 units and height 12 units. So, the area of the shaded region is equal to area of the triangle.

A=\dfrac{1}{2}\times base\times height

A=\dfrac{1}{2}\times 15\times 12

A=\dfrac{180}{2}

A=90

Therefore, the area of the shaded region is 90 square units.

In the seconds figure, we need to subtract the area of square from the area of triangle, to get the area of the shaded region.

Area of triangle with base 15 and height 18 is:

A_1=\dfrac{1}{2}\times 15\times 18

A_1=\dfrac{270}{2}

A_1=135

Area of the square with sides 6.

A_2=(side)^2

A_2=(6)^2

A_2=36

Now, the area of the shaded region is:

A=A_1-A_2

A=135-36

A=99

Therefore, the area of the shaded region is 99 square units.

A washer and a dryer cost $772 combined. The washer cost $72 more than the dryer. What is the cost of the dryer
melamori03 [73]
Dryer cost represented by x
Then, the washer costs (x + $72)
Together, they cost (x) + (x+72) = $772
2x+72 = 772
[subtract 97 from both sides]
x = 350
[divide both sides by 2]

The dryer cost $350

The washer cost $422.

Together, they cost $772

RUDIKE [14]

Answer:

3.728 cm²

90

Step-by-step explanation:

To built the envelope I am using a rectangular piece of material 28 m long and 12 m wide.  

Out of this material, I have to cut patches that are 1/12 the length and 2/15 the width of the whole material.

So, the length of the patches is 28 \times \frac{1}{12} = 2.33 m and the width of the patches is 12 \times \frac{2}{15} = 1.6 m.

Therefore, the area of the patches is (1.6 × 2.33) = 3.728 m² each. (Answer)

Now, the area of the rectangular piece of material is (28 × 12) = 336 m²

Hence, \frac{336}{3.728} = 90.37 ≈ 90 such patches can be made out of the whole material. (Answer)
